Description

The invention relates to warning complexes and loud-speaking communication and can be used to organize alerts and communications at various sites, including vehicles, for example on the railway.

A known system of automatic multi-zone speakerphone (US Pat. Of the Russian Federation No. 130741, IPC G09F 25/00, publ. 07.27.2013), containing microphone local notification panels; emergency warning equipment in emergency situations; source of attention tones; loudspeaker equipment consisting of a pre-amplifier and power amplifier; switching unit for single or multi-zone broadcasting; control system, delimiting the priority of the sources of sound alerts. The signal outputs of the microphone panels and emergency warning equipment in emergency situations are connected to the control system inputs, and the voice channels go to the sound amplifying equipment, which is further connected by sound channels in series. An automatic telephone station equipped with an interface card has been introduced to the system, while the signal channels of the interface card are introduced into a control system based on a microprocessor with programmed control, which allows you to select broadcast zones in any number and order by decade dialing and select groups of pre-programmed zones ; at the same time, voice channels go directly to the sound amplifying equipment.

A well-known system of intercom speakerphone communication and broadcasting (US Pat. Of the Russian Federation No. 2131168, IPC NVB 13/00, publ. 27.05.1999), containing in its composition switches and consoles located in different rooms and equipped with cases and panels on which controls and indications, subscriber switches and subscriber set circuitry, as well as connectors to which electroacoustic transducers are connected, external wiring cables and a secondary power source. The system additionally introduced switching centers, connected in series with each other by fiber-optic communication lines, to which switches and consoles, a broadcast unit and a subscriber line unit of telephone sets are connected. The switching centers contain subscriber modules connected by channels to the main and backup control bus, and the backup and main control bus is connected to the information documentation system, the channel's operational storage device, the synchronous generator and the trunk expander, which, in turn, is connected to the control bus, with the address bus and data bus, which are connected to both redundant and main central processors and reserve cell, while the switches and consoles contain rokontroller, switching device, transceiver, power converter, control circuit and a keyboard light.

Closest to the claimed automated multi-channel audio alert complex is adopted as a prototype automated digital warning system (US Pat. Of the Russian Federation No. 172051, IPC H04M 9/08, H04M 11/02 G08B 3/10, publ. 28.06.2017), including the device control, radio receiving device, signal amplifier, first device for converting electrical signal to acoustic, first device for converting acoustic signals into electrical, device for generating control signals, power supply, device for processing signal signals, a second device for converting electrical signals into acoustic signals, an interface device, an information display device, a time signal generating device, an access control device, and a light signal playback device. The control unit includes a microcontroller, a device for converting acoustic signals into electrical signals, an interface device, a device for generating time signals, an access control device and a device for generating control signals. The system also contains a radio transmitting device connected to the output of the control device, and a second device converting acoustic signals into electrical signals connected to the input of the control device, and the output of the power supply unit is connected to the power supply input of the radio transmitting device.

A common drawback of the known analogs and prototypes lies in their insufficiently high reliability and the associated fault tolerance, due to the loss of performance when the main functional blocks, such as the control microcontroller, signal amplifier, interface device and power supply, fail. The disadvantage is also low functionality due to the lack of monitoring and diagnostics of functional units, the ability to adapt them to various objects without changing the hardware, building up by expanding and using the existing hardware, integrating into various adjacent systems.

The main objective of the claimed invention is the creation of an automated multi-channel audio alert complex that provides centralized automated control and has high reliability, fault tolerance and wide functionality.

The technical result, the achievement of which the claimed invention is directed, consists in increasing the reliability, fault tolerance and expanding the functionality of the system by providing diagnostics and automatic redundancy of modules in the hierarchical structure of managing modules connected to each other.

The task is achieved by the fact that the automated multi-channel audio alert complex contains a power supply module connected to an amplifier / switching unit including a main control module connected to the main data bus and connected to it main amplifier modules, an interface module, and an interface module made with the ability to connect with external peripheral devices, while the amplification-switching unit additionally contains a module of terminal consoles and ne negotiation devices, at least one redundant control module, redundant amplifying module, redundant switching device to which main and redundant amplifying modules are connected, and network interconnection module capable of exchanging information between all modules and redundant switching device of the amplifier-switching unit , and the power supply module is made in the form of a rechargeable battery, the main and backup power supply devices connected to the backup device power supply from the network connected to the main and backup buses of data exchange of the amplifying-switching unit.

Optimally, the main and backup control modules of the automated multichannel complex should be performed with the possibility of diagnosing devices and modules of the complex, and the backup switching device should be performed with the possibility of diagnosing the output path and load.

The main and backup control modules can be made on the basis of the processor, which provides the ability to diagnose the state, change the settings of the modules, increase the number and number of modules and units when changing requirements for the number of warning zones at the sound objects, the number of consoles, the number of external equipment connected, and integration in various systems, for example, fire alarm systems, sound systems available, control systems and control systems for buildings, structures and technological E processes.

The backup switching device can be configured to automatically connect the backup amplifier module and disconnect the main amplifier module that has failed.

An automated multi-channel audio alert complex may contain voice and voice message playback devices.

The main and backup amplifying modules are optimally implemented with the possibility of self-testing and supplemented with a load control unit.

Optimally, the primary and backup control modules are designed to diagnose external peripherals.

The automated multichannel audio alert complex contains sound reproduction equipment connected to the interface module and acoustic devices connected to the backup switching device.

An automated multi-channel audio alert complex contains external peripherals, for example, speakers, microphones connected to a interface module.

Automated multichannel sound alert system may contain an expansion bus for joining several amplification switching blocks.

The automated multichannel audio alert complex is optimally supplemented with a redundant external bus for connecting external control equipment.

The inventive sound notification complex is based on a modular construction principle, which allows optimizing it for any object. Any signal sources (microphones, network broadcasts, telephone sets, radio bases, etc.) as well as any types of communication channels can be connected to the complex. The use of a variety of external equipment and communication channels is provided by the use of appropriate modules.

The main and backup control modules are made with a central processor based on specialized software that allows you to flexibly customize the operation of the complex for a specific task. Customization can be done by a user (technician) in a high level language.

The combination of significant distinctive features allows you to apply the method of hierarchy and redundancy of devices and modules of this hierarchy when building the proposed complex of loud-speaking alerts. This provides automatic backup of the main blocks of the complex: internal communication channels between system modules, power supply modules, central processor, and amplifying modules.

The inventive set of sound alerts has considerable flexibility, allowing you to adjust to the changes in the conditions of use with minimal cost, without replacing existing modules and devices. For example, in the case of increasing the coverage area of the loudspeaker alert (MGO), it is possible to add the necessary elements to the horizontal level of the architecture (amplifiers, loudspeakers, call consoles, etc.). If necessary, the expansion can be carried out both by expanding the composition of the existing system, and by including new, geographically remote sets of equipment connected to the main system by a redundant communication channel.

The inventive complex is universal in application, since it provides the ability to integrate into the GGO complex various adjacent systems from other manufacturers, for example, a fire alarm system, a radio communication system, telephone communication, etc.

In the inventive complex implemented centralized automated health monitoring of all composite devices and models. Objects of monitoring are both elements of the upper hierarchical level (nodal control complexes), and the level of peripheral equipment, the horizontal segment (amplifiers, loudspeakers, call panels, visual warning tools, etc.). Centralized control implies the ability to control the elements of the complex - by changing the settings and functions of the equipment from “one window”, as well as the possibility of external control of the system, which implies the possibility of including the HGO system of the target object in the hierarchy of the HGO centralized system, for example, groups of the same type (buildings, open sites) places of mass stay, etc.).

The invention is illustrated by drawings, where:

in fig. 1 shows a block diagram of an automated multichannel audio alert complex and its connections with external devices;

in fig. 2 shows a schematic representation of the algorithm for the operation of the power supply module of an automated multi-channel audio alert complex.

The automated multi-channel audio alert complex (Fig. 1) contains at least one amplifier / switching unit 1, including a main control module 2 and a backup control module 11, each of which contains a processor 3, main amplifier modules 12 and a backup amplifier module 13 The main 12 and reserve 13 amplifying modules are connected to the inputs of the backup switching device 15, the outputs of which are connected to external acoustic devices 14.

Amplifier switching unit 1 also contains an interface module 18 connected to external peripheral devices 22 (speakers, microphones, etc.), a module 19 terminal consoles and intercoms, providing information exchange with consoles 16 through two-way data exchange via a serial bi-directional standard digital interface V22 and bidirectional analog interface with a bandwidth of -3 dB at least 200 ... 5000 Hz, an interface module 20 that provides interaction with external sound equipment 23, for example, low-frequency amplifiers. The network interaction module 21 of block 1 provides for the exchange of information via the standard Ethernet interface between all modules and blocks that are part of the amplifier / switching block 1, using the main 4 and backup 17 data communication buses, as well as interaction with the extension bus 24 for connecting several amplifiers switching units 1 and with external bus 25 for connecting external control equipment. Expansion Bus 24 has two independent Ethernet interfaces to ensure system resiliency. The redundant external bus 25 also has two independent Ethernet interfaces to provide system resiliency.

The main amplifying modules 12 and the identical backup module 13 have an integrated self-testing subsystem, as well as a load monitoring subsystem (not shown in the drawings).

The backup switching device 15 is configured to automatically connect the backup amplifying module 13 and disconnect one of the main amplifying modules 12, in case of its failure.

Amplifier switching unit 1 is connected to a power supply module 5, which contains a battery 6 connected to a charging device 7 and a power backup device 8 connected to the main 9 and standby 10 power devices from the network. Module 5 power sources through the output of the device 8 backup power is connected to the main 4 and 17 backup tires 4 data exchange.

Automated multi-channel audio alert system works as follows.

On the redundant interface bus 25 with the Ethernet interface, the complex interacts with external control equipment (not shown in the drawings) through the network interaction module 21, which provides for the exchange of information between all the modules and the backup switching device included in the amplifier / switching unit 1, using the main 4 and 17 backup bus communication. The software of the main control module 2 and the backup control module 11, in accordance with the system settings, generates commands, analyzes receipts and manages digital data streams equivalent to sound signals circulating in a complex between the modules associated with the sources and / or receivers of audio information received from external peripherals 22, consoles 16 and / or from external audio equipment 23 and supplied to external acoustic devices 14.

The network interface module 21 is configured to connect and dock several amplification and switching units 1 via an expansion bus 24. At the same time, external control equipment (not shown) is connected via the redundant external bus 25, through the network interaction module 21, to exchange control commands , telemetry data and sound data in digital format with the main control module 2 or standby 11, providing switching between the modules of the complex, and using Backup switching 15 with external acoustic devices 14. Sound data from external peripheral devices 22 via interface module 18 or remote controls 16, through a module of 19 terminal consoles and intercoms are transmitted through the primary 4 or redundant 17 communication buses to one of the involved primary control modules 2 or the redundant control module 11 and further to the corresponding main amplifying module 12. The amplified sound signals through the amplifying modules 12 are transmitted by the backup switching device 15 n corresponding external acoustic device 14, and they are played simultaneously in several independent zones.

In the case of using external sound reproduction equipment 23, which is not included in the standard equipment of the automated multichannel audio alert complex, audio data for it is transmitted through the interface module 20.

The main control modules 2 use the network interaction module 21 to monitor the status of all modules in the complex, communication lines, primary 4 and backup 17 data communication buses and terminals, control and management of power supply, backup of power supply modules, backup of control modules, redundancy of amplifying modules, interaction with external equipment through standard discrete and serial interfaces.

In the process, even in the absence of sound transmission, the main control module 2 or the backup control module 11, periodically sends commands to check the status of the amplifier modules 12 with a period of at least 0.2 s. If one of them fails, if there is no corresponding receipt for a command about the status of the amplifier module 12 more than two times in a row, the main control module 2 or the backup control module 11 issues a set of commands to the backup switching device 15:

- to disconnect the corresponding external acoustic device 14 from the defective amplifier module 12;

- to enable backup amplifier module 13 to the corresponding external acoustic device 14.

The basic principle of the redundancy support algorithm of amplifying modules is the mandatory implementation of the following sequence of actions:

- if the amplifier module 12 transmits information to the main control module 2 or the backup 11 via the main data bus 4 about its own fault according to the results of self-diagnostics, or there is no interaction with the amplifier module 12 over the main communication bus 4 and the backup data bus 17, then the main module control 2 sends to the backup switching device 15 a switching command for switching external acoustic devices 14 from the output of the faulty amplifier module 12 to the output of the backup amplifier about module 13;

- the main control module 2 or the backup control module 11 performs an internal reconfiguration of the software in such a way as to switch the interaction from the faulty amplifying module 12 to the redundant amplifying module 13.

The amplifier modules 12 and the identical backup module 13 have an integrated self-testing subsystem, as well as a load control subsystem. These subsystems continuously monitor a number of control parameters (module temperature, voltage and current levels at critical nodes and load) and send the relevant information to the main control module 2 or the backup control module 11 at specified intervals. In case of exceeding the control parameters of the specified levels, the main control module 2 or the backup control module 11 decide to change the mode of operation of the corresponding amplifying module 12 or 13 or to turn it off for the purpose of being saved I performance of the entire system.

This process is performed for a period of time not exceeding 0.2 s, which does not lead to a noticeable disturbance of the sound broadcast. Simultaneously, from the main control module 2 or the backup control module 11, via the redundant external bus 25, the upper control level receives information about the malfunction of a specific main amplifying module 12, which allows you to quickly perform repairs by replacing the failed amplifying module with service personnel.

Duplication and switching between the main 2 and backup control modules 11 is carried out using the specialized software installed in the central processors 3, which are part of the control modules, which functions in each of these modules at the same time and provides continuous monitoring of both the module's own operability and performance others included in the complex modules. When a failure of the main module 2 occurs, the control is assumed by the backup control module 11, and the modules are configured to diagnose all devices and modules of the complex. The main control module 2 and the backup control module 11 (Fig. 1) carry out diagnostics based on automated monitoring of the state, changing the settings of the modules included in the automated multi-channel complex of sound alerts and increasing the composition of the modules and blocks to the complex if necessary to increase the total power of the sound alert, the number of sound zones, the number of connected consoles and other equipment, integration into various adjacent systems and automatic reserve communication channels between modules.

This feature is implemented through software modules that support redundancy algorithms embedded with software. The basic principle of the channel reservation algorithm is to continuously perform the following sequence of actions:

- interaction takes place between the main control module 2 or the backup control module 11 and any of the slave modules, for example, the interface module 18 on the main data bus 4;

- checks the condition of the presence of a response from the interface module 18 on the main data bus 4;

- if there is a response and the health of the interface module 18, the interaction with it is then carried out via the main bus 4 of data exchange;

- in the absence of a response from the interface module 18, the primary 2 or the backup 11 management modules interact with it via the backup data bus 17;

- if there is no response from the interface module 18 and via the main data bus 4 and the backup data bus 17, this module is considered faulty.

The algorithm of operation of the power supply module 5 (Fig. 2), carried out by the power backup device 8, provides continuous fail-safe power supply to the amplifier / switching unit 1 by means of the following program blocks for checking the conditions: monitoring the line voltage (1), monitoring the battery voltage (battery) (2 ), the control of the health of the main power device 9 (in FIG. 2 - the PMO 9) from the network (4), the control of the health of the backup power device (in FIG. 2 - RUP 10) from the network (6). After checking the specified conditions, the corresponding program blocks of actions (3), (5), (7), (8) are executed as follows.

In the absence of the mains voltage and the normal voltage on the battery 6, the operation of the amplifying-switching unit 1 is carried out from the battery 6, and the sequence of actions 1-2-3 (Fig. 2) is performed and the transition to the beginning of the algorithm is performed. In the presence of mains voltage and the health of the main power supply device 9 from the network, the operation of the amplifier-switching unit 1 is performed with its help, the backup power supply device from the network 10 is in reserve, the sequence of actions 1-4-5 is performed and the transition to the beginning of the algorithm is performed, which is necessary for continuous testing of the health of the main device 9 from the network.

In the presence of mains voltage, malfunction of the main power supply device 9 and the health of the backup power supply device 10 from the network, the amplification and switching unit 1 is operated from the backup power supply device 10 in the sequence 1-4-6-7 (Fig. 2) and jump to the beginning of the algorithm. In case of malfunction of the mains supply device 9 and the backup power supply device 10, the condition for checking the voltage of the battery 6 is made and only in the case of a lower voltage below the preset threshold, the power of the amplification and switching unit 1 is turned off, and the sequence of actions 1-2- is performed 8, as a result of which a transition is made to the beginning of the algorithm, with the power cut-off of the amplifier-switching unit 1.

The complex provides the sending of information on the status and performance of all the modules included in it to the upper control level, for example, an automated workplace under the control of the operator. This information is the basis for prompt repair and restoration of the complex by replacing defective modules with service personnel in the shortest possible time.

The design of the complex is built in such a way that each module is made in the form of a quick-detachable hardware unit installed in the crate (basket) of the amplifier-switching unit 1 and replaced during no more than 1-3 minutes. It does not require any additional actions to configure it.

The modular principle underlying the construction of an automated multi-channel audio alert complex makes it possible to optimize the task of providing a loud-speaking alert for objects of various purposes and complexity. The claimed complex can be connected via the expansion bus 24, the network interaction module 21, the interface module 20, the reserved external bus 25 and the interface module 18 with external peripheral devices and various signal sources (consoles, microphones, network broadcasts, telephone sets, radio bases, etc. .), as well as various types of communication channels. The use of a variety of external equipment and communication channels is provided by the use of appropriate modules. The network interaction module 21 and the main control module 2 and the backup 11 are equipped with specialized software that allows you to flexibly customize the behavior of the system for a specific task. Customization is done by a user (technician) in a high level language. This provides significant flexibility of the claimed, which significantly expands its functionality and allows for a minimum cost to carry out the restructuring under the changed conditions of use, without replacing existing elements. For example, if it is necessary to increase the coverage of the loudspeaker alert area, the complex is scaled by adding the necessary elements to the horizontal architecture level (main amplifying modules 12, external acoustic devices 14, remote controls 16, external peripheral devices 22, etc.). If necessary, the expansion can be carried out both by expanding the composition of the proposed complex, and by including new, geographically remote sets of equipment, for example, amplification and switching units 1, connected to the main system by a redundant communication channel.

The ability to integrate into the complex various adjacent systems from other areas of technology, for example, a fire alarm system, a radio communication system, a telephone communication system, etc., provides a significant expansion of the functionality of an automated multichannel sound alert complex

The claimed invention contributes to the creation of an automated multi-channel audio alert complex with high reliability, fault tolerance and wide functionality.
